README

Operator reference implementation

sample-operator controls deployment of a simple, not customized nginx HTTP server.

Deployment

sample-operator is deployed in kubevirt namespace and deployment manifests will create it, if it's not present.

To deploy the operator execute following command:

kubectl apply -f manifests/v0.0.3/operator.yaml

Deployment of the HTTP server is controlled by the presence of a sampleconfig CR; to deploy it, execute:

kubectl apply -f manifests/v0.0.3/sampleconfig_types.go

The HTTP service listens on port 8081, which in turn is exposed as a node port 30080.

In case of deployments like CRC or kubevirtci, port forwarding might be required:

kubectl -n kubevirt port-forward service/http-server 8081:8081

To upgrade the HTTP server deployment, change configuration of the sample-operator container in the spec.template.spec.containers array of sample-operator deployment.

Building the sample operator

For convenience Makefile has been provided that helps with testing, building and publishing of the operator:

• make docker-build will build both operator and HTTP server images (by default: quay.io/$USER/sample-operator:latest and quay.io/$USER/sample-http-server:latest)
• make docker-push will push both images to the remote repository;
